*                         3rd edition of ISO 646, specifies several versions of a 7-bit character set :
*
*                         (1) THE GENERAL VERSION, which allows characters at 0x23 and 0x24 to be given a
*                             set alternate form and allows the characters 0x40, 0x5B, 0x5D, 0x60, 0x7B &
*                             0x7D to be assigned a "unique graphic character" or to be declared as unused.
*                             All other characters are explicitly specified.
*
*                         (2) THE INTERNATIONAL REFERENCE VERSION, which explicitly specifies all characters
*                             in the 7-bit character set.
*
*                         (3) NATIONAL & APPLICATION-ORIENTED VERSIONS, which may be derived from the
*                             standard in specified ways.
*
*                     (b) The character set represented in this file reproduces the Internation Reference
*                         Version.  This is identical to the 7-bit character set which occupies Unicode
*                         characters 0x0000 through 0x007F.  The character names are taken from v5.0 of the
*                         Unicode specification, with certain abbreviations so that the resulting #define
*                         names will not violate ANSI C naming restriction :
*
*                         (1) For the Latin capital & lowercase letters, the name components 'LETTER_CAPITAL'
*                             & 'LETTER_SMALL' are replaced by 'UPPER' & 'LOWER', respectively.
